well, im not sure if there's time to arrange 3rd place decider inbetween semifinal/grand final because of other games which are to be played at the main stage(Point Blank grand final for example, which should start soon)

TR15%-85%Na'Vi
If Na'Vi plays with in the same mood as against Mouz, PGG will get his butt kicked.
TR played really inconsistently during this tournament so there's also possibility that this grandfinal is going to be really one sided(I wouldn't say boring, Na'Vi always makes the game entertaining), because when you combine Na'Vi at their best and PGG's mix at his worst you'll get even bigger stomp then Natus vs. Mouz. (Like that's even possible:) So TR should hope for some mistakes from the Ukrainian team, if they want to think about winning the trophy.
